Create Surface from Selection
what @ZargulTheWizard is trying politely saying to you is that your Blender knowledge could be a little bit more advanced. You are assuming too much with too less knowledge.
&quot;A common object type used in a 3D scene is a mesh.&quot; (from Blender docs). A mesh consists of vertices (points), edges (connections between points) and faces.
&quot;face
A closed set of edges, in which a triangle face has three edges, and a quad face has four edges. A polygon is a coplanar set of faces. In systems that support multi-sided faces, polygons and faces are equivalent. However, most rendering hardware supports only 3- or 4-sided faces, so polygons are represented as multiple faces. Mathematically a polygonal mesh may be considered an unstructured grid, or undirected graph, with additional properties of geometry, shape and topology.&quot; (from wikipedia)
With &quot;F&quot;

you can create an edge between two selected vertices
you can create a single(!) face between more than two selected vertices

Answer to your assumption: &quot;I would expect to see something new in my Scene Collection, nope. When I pop over to the Shading pane, nothing new to see, in fact, the disappearance of the geometry is the only indication that something (who knows what) happened.&quot;:
But if you created edges or faces, you just change the mesh of an object, you do not create new objects at all which you could see in the outliner (scene collection).
If you just see points as in your last posted picture you just have vertices. Nobody ever would then press &quot;F&quot; to create one single face because that are way too many vertices and it would look like shit.
Next to your sentence:
&quot;In the Modeling pane I've selected the first part of the model that I want to isolate and I believe I want to create a Surface so that it can then be shaded.&quot;
-&gt; in the picture you posted to that you already have a surface (which is called faces in Blender -&gt; try to use the right terms, else there will be lots of misunderstandings). You can &quot;see&quot; the faces by the gray color. The dots are the vertices and the &quot;lines&quot; are the edges.
Hopefully this helps you a bit. Maybe you should watch some beginner tutorials like here...
